Hybrid solutionHybrid solutionDynamic and flexibleDynamic and flexibleUse drive-by for the majority of water &
electric residential and small commercial customers, can be upgraded to fixed network as business needs change
Use wireless communication technology for dormitories and high turnover apartments with two-way communication for connect/disconnect, pre-pay and other broadband services
Use wireless communication with load interval data for large commercial and industrial customers.

Technology Challenges
Prior to the installation of SmartMeter System
Recorders placed on 2,000 meters throughout the system to capture fifteen minutes LP
Data was manually retrieved once a month Each recorder was visited and read by a meter
reading personnelData was manually up loaded to the LADWP

Key Benefits
Have the flexibility to implement real-time pricing, TOU, critical peak pricing, and demand response tariffs for medium and large customers.
Produce dynamic load profiles of each rate class for more accurate cost-of-service studies as mandated by the CEC.
Support special contract accounts. Design rates to collect revenue based upon actual cost of
service rather than the average cost. Enable creation of tariffs that are tailored to meet the needs of
individual or segmented customer groups. Provide information over Internet, including energy costs, actual
individual’s usage, and typical usage by time of day. Customers will have the ability to view detailed energy usage

AMI Program: OPPORTUNITIESOPPORTUNITIES
With the new Rate Analysis System, large commercial customers with wireless meters could be billed directly.
Customers could be offered calendar month billing and customized bills sent electronically.
Gas Company is installing 100k meters in the Los Angeles area and would like to coordinate with LADWP.
WIFI – Pilot Project to install WIFI meters in conjunction with the Mayor’s wireless plan for the City of Los Angeles
Net Metering – Install wireless meters for Solar Installations to provide customers billing with more detailed information such as energy generated, energy used and value of energy generated

Conclusion
LADWP realized operational and financial benefits by deploying the system and collecting interval data from existing smart meters
Value of real time interval data provides Opportunity for Demand response and load curtailment programs
Plans to expand deployment of Smart Meter programs to C&I customers
